| Summary | ULA's workhorse since 2002 and the longest-serving active US rocket. Launched Mars Science Laboratory (Curiosity), OSIRIS-REx, Solar Orbiter, Lucy, New Horizons, and the Boeing Starliner. Production ended in 2024 and ULA no longer sells the vehicle, but it continues flying a sold-out backlog of Starliner and Amazon Leo missions into the late 2020s. | Europe's flagship launcher replacing Ariane 5. The Vinci re-ignitable upper stage enables multi-orbit missions and controlled deorbit. Primary customers: Amazon Kuiper, European government payloads, and ESA science missions. | A family of medium-lift launchers from SAST serving China's growing SSO/LEO commercial and government satellite demand, with the 6A and 6C variants adding solid boosters or a simplified expendable configuration respectively. |
